T all whom it main concern Be it known that 1, JOHN NAmzZANo, of HamptonlVick, in the county of Middlesex, England, a subject of the King ofItaly, have invented certain new and useful limprovements in or Relatingto Machines for Covering Wire with Silk, Cotton, or the like, of whichthe following-is a specification.

This invention relates to machines for covering wire with silk or thelike, of the type in which a series of spinner heads are provided havingflye-rs adapted to rotate about a horizontal or substantially horizontalaxis, each pair being provided with a separate drive, and series oftubular bob bin holders are disposed in front of each spinner head tohold spare bobbins, so that when one bobbin is finished a new one can bemoved from the holder to the spinner head.

The object of the invention is to provide an improved constructionadapted to facilitate the operation of machines of the kind indicated.

My improved machine comprises features constituting a substantialdeparture from the standard construction heretofore employed, and alsovarious known elements in combination as hereinafter described andspecifically claimed.

Referring to the drawings filed herewith Fig. 1 is a front elevation,broken away of a machine made in accordance with this invention;

Fig. 2 is an end elevation;

Fig. 3 is a transverse section.

On the frames a a of the machine are mounted a main shaft 6 and acounter shaft 0. On themain shaft 6 are mounted fast and loose pulleyscl a toothed pinion e and a. series of grooved pulleys f f. On one framea is also mounted an arm 9 on which is dis posed a train of change speedgear wheels h j 70 and a removable pulley m, the diameter of whichvaries according to the speed at which it is desired to drive thecountershaft 0. The arm 9 is also fitted in such a way that it can withits gear wheels be moved radially aboutthe centre of the shaft 6 inorder to compensate for the slackening of the belt p caused by thechanging of the pulleys m.

On the shaft 0 are mounted a series, of grooved wheels 12 and a pulley 0adapted to be driven from the pulley m by a belt 39.

On the frame a of the machine are two beams 1" a on which are mounted aseries of pairs of spinner heads 25 25 arranged one in advance of theother provided with flyers ii, Z, and a series of hangers o o. On thehangers o o are mounted grooved pulleys w w. A driving cord x passesover each pulley 7 over two pulleys y y on the flyers and over thepulleys w wso that the spinner heads on the beam o rotate in theopposite direction from the spinner heads on the beam 8.

' On the frame a is mounted a beam 2 on which are disposed arms 3carrying grooved pulleys t and 5 and winding up bobbins 6. The bobbins(3 are each driven separately by a cord 7 passing over the groovedwheels n and the corresponding pulleys 1 and 5.

The beam .9 carries a series of tubular bob- 3111 holders 8. On theframe a is a beam 2 on which are mounted a series of guide pulleys 10and bobbin holders 11. On the frame of this machine is mounted a beam 12carrying studs 13 each adapted to carry a spool 14: of wire to becovered. on the frame a is mounted a small shaft 15 on which aredisposed loose guide pulleys. The wire 17 is led through the spinnerheads 16 and bobbin holders 8 and 11 once round the pulley a through theguide 18 to the bobbin 6, the guides 18 are moved from left to right andvice versa on the rod 29 which obtains its motion through the crankarrangement 30 operated by a worm gear 31 from the countershaft c.

On each stem 13 is a hollow spindle 19 carrying a pulley 20 on which isdisposed a cord 21 adapted to be kept taut by a weight or spring and.adapted to act as a brake on the spools 1 1 and prevent theiroverrun-hing.

The spinner heads are held in position by plates 22 adapted to clamp thespindles of the heads on to the beams r and a.

23 is a striking rod mounted in brackets 2 1, 2 1, and adapted tooperate the striker 25 through lever 26 rocking shaft 27 and crank 28.

The bobbins on which the covering material is wound are provided with aslit or adapted to be cut so that when empty the wire can be slippedthrough the slit when it is desired to remove it and place a full bobbinon a spinner head.

In use a bobbin of silk is placed on each spinner head and spare bobbinsare placed on the holders. hen a bobbin is finished a spare bobbin ismoved from the holder to the spinning head so that a long length of Wirecan be covered without having to cut the wire to insert a new bobbin ofcovering material on the spinner head. The machine shown is for doublecovering but single covering can be eli'ected by the machine in whicheach pair of spinner heads, a series of tubu lar bobbin holders eacharranged in axial alignment with one of said spinner heads forsupporting spare bobbins, and. mechanical means for varying the relativespeed of the flyers and the Winding bobbins.

2. In. a machine for covering Wire, the

combination of a plurality of flyels, a pinrality of winding bobbins,means "for driving the ['lyers, means for driving the Winding bobbins,an arm shiitable radially of said bobbin Winding means, and a removablemotion transmitting member carried by said arm for varying the relativespeed of the flyers and Winding bobbins.

3. In a machine of the class described, the combination of a pluralityof fliers, a main driving shaft for driving the flyers, an arm pivotallymounted thereon, a plurality of Winding bobbins, a countershatt fordriving the Winding bobbins, means carried by said arm for transmittingmotion tromsaid main shaft to said countershaft, and means for adjustingsaid arm radially of said countershatt thereby to permit variation ofthe speed of the countershaft relative to that of the main shaft.

In testimony whereof I have signed my name-to this specification.

JOHN NARIZZANO.
